Who sells sodium bicarbonate tablets?

Until recently, sodium bicarbonate tablets were primarily manufactured by Concord Labs. in New Jersey. They were distributed by a number of companies including URL labs and were sold in bottles containing 100 or 1000 tablets in 5 or 10 grain portions. It appears that Concord Labs has been closed by the FDA as a result of several violations. At this time it is almost impossible to find these tablets. Pharmacists report that they are not available or are on "backorder".

Sodium bicarbonate is baking soda. You can find it at any grocery store.
